NBC has ordered a new untitled medical drama to pilot. The potential series, formerly working under the title ?Salvation,? is written and executive produced by Warren Leight, with Charles McDougall directing and also serving as an EP along with Paul Haggis. The project is described as a real time ?extreme event? medical series that follows the nurses and doctors of an understaffed Brooklyn hospital that becomes the borough?s last viable trauma center after a catastrophic hurricane wreaks havoc on the city.
